' This invention ,relates to improvements in mopping machines designed for scrubbing iioors or similar surfaces, and is. of ythat general type including -a reservoir for-icontaining the cleaning water VYand `means for y An important object of the improvement is :the construction of the rotary Isqueegee, wherein a plurality ,of wedging surfaces .are provided for successfully `acting upon .the mops for squeezing the water therefrom, a series of pockets lbeingiformed in the rotary squeegee communicating with the wedging surfaces to receive the dirty water squeezed from the mops and transfer the same to the tank provided for that purpose.

The above and other objects may be attained by constructing the machine in the manner illustrated in the accompanying drawing, in which-- Figure 1 is a longitudinal sectional View through the improved mopping machine;-

Fig. 2, a section on the line 2-2, Fig. 1; and

Fig. 3, a fragmentary sectional View showing the gearing designed for operating the mopping mechanism by traction.

Similar numerals refer to similar parts throughout the drawing.

The housino` 1 of the machine may be of metal or woodl, and is provided in its lower portion with the rearwardly disposed projection 2. The front and rear walls of the housing may be inclined toward each other at their upper ends as at 3 and 4 respectively, terminating in the reduced upper portion 5, provided with a removable cover 6.

The cleaning water receptacle 7 is located in the upper reduced portion of the housing, a ledge 8 upon the rear wall supporting the rear portion of said receptacle. A reduced portion 9 communicates with the forward side `of the reservoir, extending downward and forward along the inclined portion 3 and then downward at an angle communicating with the enlarged cylindrical portionV 10 located in the lower forward part ofthe-casing.

The cylinder c10 is iprovided ywith perfora-l tions 11i-n its' lowverfsideto permit `the cleaning water ftobe discharged upon 'the floor .or otherA :surface over Ywhich the machine is passed.

For the :purpose 'of :controlling fthe flowV of water, awalve,isprovided which vmay be in the ifonmfof aspht eylindric slide valve 12 mounted lfor, rotation around the axis ofwthe cylinder f10,andprovided with aliandle 13 extend'ingthrough a slot 14 -in the front portion'of thecasing. As shownin Fig. 1, this valvemay be operated toentirely close the apertures 11 vif desired. ,Y

Tllhe y'housing y,1 liamounted upon .rollers y15V inordeiutha-t-the machineanay bermo-ved over the floor .as by a handlek 16, Avbail lmay be Y:connected yto the ,upper 4`portion of ,the housing for lifting the mopping machine when lit .is rdesiredj to v`transport -,the same-from place to place.

The rotor 18 is mounted upon a shaft 19 journaled through the side walls of the housing. This rotor is provided with a plurality of arms 2() having the clamping plates 21 carried at their end portions by means of the clamping screws 22. A mop 23` is clamped beneath each of the clamping plates and arranged to extend over the end of the arm as shown.

The rotary squeegeeis shown at 24 and is fixed upon a shaft 25 journaled through the side walls of the housing and parallel to the rotary shaft 19. This rotor is provided with a plurality of wedge shaped radial ribs 26, the outer edge of each of which is curved as shown at 27, pockets 28 being provided between the ribs. An end plate 29 is pro-V vided at each end of the rotor in order to retain water in the uppermost pockets, as shown in Fig. 1.

A tank 30 is mounted upon, the shelf 31 located in the lower portion of the reduced e'xtremity 2 of the housing, to receive the dirty water which is squeezed out of the mops by the rotary squeegee. This tank is slidably mounted upon the shelf31 and provided with a handle 32 by means of which it may beremoved when it is necessary to empty the' water therefrom.

Therotor and squeegee may be operated by a motor 33 as shown in Fig. 2. A sprocket 31 may be fixed upon the shaft 35 of the motor and connected by a sprocketk chain 36V with a sprocket 27 uponthe shaft 19 of the rotor.

In the operation. of the machine, the handle 13 of the valve 12 is moved in a direction to expose the apertures 11 in the under side of the cylinder 10, permitting a spray of water to be played upon the floor within the forward portion of the housing.

As the machine is moved across the fioor by means of the handle 16, `the rotor will be turned in the direction of the arrow shown in Fig. 1, the mops 23 thereon successively wiping the dampened `floor, cleaningV the same and taking up the water therefrom, and as each mop engages the rotary squeegee, the same will be wedged between the arcuate surface 41 of the rotor and the wedge surfaces 27 upon the squeegee, squeezingthe dirty water from the mop into the pockets 28 of the squeegee, the water being discharged from these pockets into the tank 30 as illustrated.

`In Fig. 3 is shown a method of operating the rotor and rotary squeegee by traction of the machine upon the floor. The traction wheel 42 is journaled upon a stub shaft 43 fixed in one side wall of the housing and arranged to frictionally engage the floor or other surface to be cleaned. A gear 44 is fixed to the traction wheel 42 and meshes with the pinions 45 and 46 mounted upon the rotary shaft 19 and squeegee shaft 25 respectivel VIt will t ius be seen that as themachine is moved across the floor, the wheel 42, frictionally enfraging the floor, will be rotated and throng the gear 44 and pinions 45 and 46, the rotor and squee ee will be rotated in the same direction as sfrhown in Fig. 1.

`Ar mopping machine including a rotor, mops carried by the rotor and` arranged to contact with the floor, a rotary squeegee provided with pockets and arranged to engage the mops to squeeze water therefrom, a receptacle located beneath the squeegee, and means for rotating the squeegee and rotor in the same direction regardless of the direction of movement of the mopping machine.

Intestimony that I claim the above, I have hereunto subscribed my name.
